Parameter

A value that summarizes a characteristic of a population or a statistical model.

Confidence Interval

A range of values, derived from sample statistics, that is likely to contain the value of an unknown population parameter, expressed with a certain level of confidence.

Confidence Level

A confidence level is a statistical parameter that expresses how certain one is in the results of a statistical experiment, often represented as a percentage that quantifies the probability that the true parameter lies within the confidence interval.
